Summary

Bladder-neck preservation during radical prostatectomy can reduce strictures and improve continence. This technique does not compromise cancer outcomes, even in high-risk patients.

Area of Science:

Surgical Oncology

Background:

Radical prostatectomy for prostate cancer aims to eradicate malignancy while minimizing treatment side effects.
Preserving the bladder neck during surgery is a key consideration for functional outcomes.

Purpose of the Study:

To evaluate the impact of a bladder-neck preservation technique during total prostatectomy on oncologic outcomes and functional recovery.
To assess the risk of positive margins and anastomotic strictures with bladder-neck preservation.

Main Methods:

Analysis of 676 consecutive total prostatectomies.
Evaluation of tumor proximity to the bladder neck margin.
Correlation of bladder-neck margin status with preoperative prostate-specific antigen and Gleason score.

Main Results:

Bladder-neck preservation was associated with reduced risk of anastomotic stricture and faster return of urinary continence.
4.3% of patients had tumor touching the bladder neck margin; only 1% had this as the sole positive margin.
Patients with positive bladder neck margins often had high preoperative prostate-specific antigen (>10) and Gleason score (≥7), indicating preservation did not compromise oncologic control.

Conclusions:

Bladder-neck preservation is a safe technique in radical prostatectomy, offering functional benefits without compromising cancer cure.
Extensive resection of the bladder neck is unlikely to improve curative rates and may increase morbidity.
